AA modal value
BA range value
CA z-score value
DA median value
Answer & Solution
Correct answer: C. A z-score value
1. A test statistic converts the sample result onto a standard scale.
2. The calculator not only calculates the p-value but it also calculates the test statistic for the sample mean.
3. That test statistic is a z-score.
4. The z-score and the p-value carry the same information in different forms.
5. Medians, modes and ranges are descriptive statistics rather than test statistics.
